Ganglia
| Definition: |
Clusters of multipolar neurons surrounded by a capsule of loosely organized CONNECTIVE TISSUE located outside the CENTRAL NERVOUS SYSTEM. |
| Notes: |
GEN or unspecified; prefer specifics; wrist ganglion is indexed under WRIST (IM) + SYNOVIAL CYST (IM); |
Ganglia Categories.
 |
Ganglia, Autonomic - Clusters of neurons and their processes in the autonomic nervous system. In the autonomic ganglia, the preganglionic fibers from the central nervous system synapse onto the neurons whose axons are the postganglionic fibers innervating target organs. The ganglia also contain intrinsic neurons and supporting cells and preganglionic fibers passing through to other ganglia. |
|
Ganglia, Invertebrate - Clusters of neuronal cell bodies in invertebrates. Invertebrate ganglia may also contain neuronal processes and non-neuronal supporting cells. Many invertebrate ganglia are favorable subjects for research because they have small numbers of functional neuronal types which can be identified from one animal to another. |
|
Ganglia, Sensory - Clusters of neurons in the somatic peripheral nervous system which contain the cell bodies of sensory nerve axons. Sensory ganglia may also have intrinsic interneurons and non-neuronal supporting cells. |
|
Satellite Cells, Perineuronal - The non-neuronal cells that surround the neuronal cell bodies of the GANGLIA. They are distinguished from the perineuronal satellite oligodendrocytes (OLIGODENDROGLIA) found in the central nervous system. |
